I've been spending about an hour decoding the lettering on the Ishiman briefings, and I'll post my findings here. Big warning: There is no difference between an Ishiman S and T, and an Ishiman B and J. Other than that and a couple phonetic differentiations, it's all English in their letters. It should also be noted that sometimes the Ishimans abbreviate a name to its first four or eight letters.
If you want to figure it out for youself, continue looking at a new clue until you have all the letters. If not, I'll have a (url="http://"http://caalaklael.tripod.com/cheatsheet")cheatsheet(/url) available within a couple days.
